BOX Two Freewheel

The 9-pawl system provides 108 points of engagement, which translates to a very tight 3.3-degree engagement angle. This means your power transfer is nearly instantaneous when you start pedaling, which is crucial for quick acceleration out of the gate in BMX racing.

Yes, you will need a specific freewheel removal tool designed for four-notch single-speed freewheels, such as the Park Tool FR-6. Standard cassette tools will not fit this component.

The tooth count determines your gear ratio. A 16T freewheel will give you a 'harder' gear that is better for maintaining top speed on long straights, while an 18T will provide easier acceleration, which is often preferred for tighter tracks or getting up to speed quickly.

This freewheel is designed for single-speed BMX drivetrains. It is compatible with standard 1/8-inch BMX chains, but it will not function with the narrower chains used on multi-speed mountain or road bike drivetrains.

While it is engineered specifically for the rigors of BMX racing, its durable steel construction makes it robust enough for dirt jumping. However, if you are doing heavy street riding with frequent grinds, you may want to consider a dedicated street-specific hub or freewheel.
